a7a04d8ae6 Refactor the logic for testing if an instruction is dead into a 
separate method.

49becd6c31 Set SetStore to false, to allow this pass to delete 
dead loads.

0cf7b31c69 Add a method to MachineInstr for testing whether it makes 
any volatile memory references.

f942615847 Properly handle 'm' inline asm constraints. If a GV is being selected for the addressing mode, it requires the same logic for PIC relative addressing, etc.

b39defd763 Move FN_NOTE_AlwaysInline and other out of ParamAttrs namespace. 
Do not check isDeclaration() in hasNote(). It is clients' responsibility.

Function Notes also. Function notes are stored at index ~0.

583938816c Now that DeadMachineInstructionElim is basically working 
correctly, it's not necessary to explicitly remove registers
from their use-def lists.

01a070f9c7 Arrange for FastISel code to have access to the MachineModuleInfo 
object. This will be needed to support debug info.

3242b7c44c Track local physical register liveness. This is not the most 
efficient implementation possible, but it's pretty simple and
good enough for the time being.

track of the number of live registers, which is all the set was
being used for.

6bed18a334 Move the code for initializing the global base reg out of 
X86ISelDAGToDAG.cpp and into X86InstrInfo.cpp. This will allow
it to be reused by FastISel.

67df9bc5b8 Significant improvements to the logic for merging live intervals. This code can't 
just use LI::MergeValueAsValue, as its behavior in the presence of overlapping ranges
isn't what StrongPHIElimination wants.
